4 simple rules to ensure clean air and efficient system performance
Mechanical ventilation units (MVHR) or air handling systems are essential to keep indoor spaces well-oxygenated, healthy, and pleasantly fresh.

At the core of their proper functioning are the filters, which play a dual role:

• External filters: purify incoming air by capturing dust, pollen, and other pollutants.
• Internal filters: protect the unit by filtering air drawn from the room, preventing dust build-up inside the machine.

This makes filters a key element in ensuring indoor air quality and maintaining overall comfort.

But how often should they be cleaned or replaced?
There’s no one-size-fits-all rule, it depends on the level of air pollution, both outside and inside. Still, there are a few best practices worth following.

Here are 4 simple tips to keep in mind:
1. Initial check
After installation, check the filters regularly to determine how often maintenance is needed, based on your specific location and environment.

2. Signs of abnormal operation
Watch for increased noise or reduced airflow:

• with variable-speed fans, the unit will work harder to compensate for a clogged filter.
• with fixed-speed fans, less fresh air will enter the rooms due to filter obstruction.

3. Perceived air quality
If the air feels heavy or stale even when the system is on, the filters may be dirty and no longer ensuring proper air exchange.

4. Monitor system alerts
If your unit has a control panel, it may signal when it’s time for filter maintenance, don’t ignore these warnings!

With just a few simple checks and regular maintenance, your MVHR system will always perform at its best, ensuring a healthier and more comfortable indoor environment.
